STONE, GRANITE, OR MARBLE CUTTING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 725,301, dated April14, 1903.

I Application filed October 7, 1902.1Serial No. 126,332. (No model.) I

To all whom it may concern: U

Be it known that I, SAMUEL WALTER VINT, a subject of the King ofGreat'Brit-ain and Ireland, whose postal address is Ash Croft,

Underclifie, in the city of Bradford, England,

have invented certain new and useful Improvements in Stone, Granite, orMarble Outting Machinery, of which the following visa,

specification.

This invention relates to certainimprovements in stone, granite, andmarble'cutti'ng machinery, and has for its object the automatic feed andmore even supply of 'sand'and able, and the faces of the cuts'are smoothin. some places and rough in others. The water suitablemesh.ThelathsMaresuspendedfrom and sand once used is wasted.

In describing my invention in detail reference is made to theaccompanying sheet of drawings, similar letters indicating similar partswhere they appear, in which- Figure 1 represents a plan of a portion ofa stone-sawing machine with my1improvechine I attach in any convenientmanner three cross-beams B, B, and B Mounted on the upper side of -thebeam B and about the center of the same is a vertical support or shaftC, at the. top of which is mounted a circular or other convenient shapedvessel D, the whole beingfree to revolve. To the upper portion of thevessel D is attached a grooved pulleyE of suitable diameter. The vessel,pulley, and shaft may be supported by a bracket or the like E near thetop, as may be found most convenient, in order to insure rigidity.Leading from the vessel D in an outward and downward direction are oneor more pipes F r of convenient size. Mounted on the before- -.mentionedbeamsB, B, and B and below the ends of the pipesF is what may be termeda wheel-rim? G, which is of about the same :diameter as the circledescribed by the pipes when in motion. The Wheel-rim G on its uppersurface-is divided into small hoppers H forits-entire surface, and thesides of the wheelrim G are continued upward, forming one hopper for thetotal circumference of the same, as shown in Figs. 3 and 4. In thecenter of each hopper and at the bottom of the ,same is bored a hole J,leading from whichis a'flexible tube K of suitable length or otherconvenient means for-conducting the water and sand or the like on to thesaw-gates, which may be placed in the required position over thesawgates and held in position by laths M, suspended horizontally overthe stone, the said laths having bent wires or staples N on the upperside, through which the tubes K may be passed andbe .held in position. I

.In place of the laths M and the bent Wires or staples N, I may useordinary wire-netting of the'beam's B B by rods or the like 0, hinged atP. The said laths M may, if required, be 'driven in any convenientmanner and given a backward-and-forward motion about the length ofthestroke of the machine. On the saws Lbeing put into operation the pulleyE, attached to' the before-mentioned vessel D, whicl1,.with the"pipes F,revolves, may be driven in any convenient manner. The water and sand orthe like passes through a pipe Q, through an orificeR in the pulley E tothe vessel D, and down through the pipes F to ,the hoppersI-I. Fromthereit is conducted to the saw-gatesby the flexible tubes K and a constanteven supply maintained. The material used after being fed to thesaw-gates is collected below in any convenient manner and taken away bya drain to a sump and from there is elevated by an ordinary elevator anddelivered through the pipe Q to the vessel, and so on to the saw-gatesagain.

Under the before-mentioned process the faces of the stone out areuniformly smooth. The saw-blades last longer, as'they do not come incontact with the stone sawed, the sand or the like being always betweenthe cutting edge of the saw-blade and the stone. I in the manner and forthe purpose as herein- :0 An even supply of Water is given to the Wholebefore described and shown. length of each saw-blade. In witness whereofI have hereunto set my Vhat I claim as my invention ishand in thepresence of two witnesses. 5 11 stone, granite, and marble cuttingmachinery, a vertical support or shaft 0, vessel l SAMUEL VINT' D, pipesF, wheel-rim G, divided into hoppers Witnesses: I-I, flexible tubes K,laths M, with means for' CLIVE WAUGH, holding the tubes K in position,substantially JOSEPH P. KIRBY.
